I'v been camping in Fort Wilderness for the past 6 years. Been ther 12 times. I can't think of a campground that comes close to it. I have two kids, 6 + 9. We have the portable tv-vcr that we use. Put in a video and you don't hear a word for two hours. They love the campfire program with Chip and Dale, the outdoor movie that follows along with two pools, tennis, bike and boat rentals, fishing, and too much more to list. I take the drive from New York (Poughkeepsie Area) and it takes about 24 hours for me. This includes rest stops for the kids to use the bathroom, stopping to eat and stopping for gas.
Fort Wilderness is a little pricey depending on when you go. We usually go in January and August. Last August we were sent a postcard to come down for $29 a night. In january it is in the fort-five dollar range. If you join the Magic Kingdom Club for $39 you save 10% off the rates. For more info on Disney, I found a really good site- www.wdwig.com. Good Luck and enjoy the trip!

Can't agree more with everything that has been said here already. It will be a wonderful experience.
I take two days to go down from RI and usually stay in the Carolinas overnight, depending on how early we leave and how traffic is down through Delaware/Maryland.

I'll echo everything. We went to Ft. Wilderness every year (at Thanksgiving) from when our youngest was in a stroller until our oldest was ready for college. The best campground ever, and the best way to see Disney. I can hardly wait until grandchildren start popping out so I can start all over again! There was a thread here a couple months ago with some good advice on which loops are best, etc. Just do a search for "Disney World Camping."
